[Boost-build] no-op thread variants on linux?

Hi!

By default, boost builds debug and thread variants. However, on linux at 
least, only two of the actual boost libraries that are built for the 
thread variant actually use threads: libboost_thread-mt and 
libboost_regex-mt. (Via an admittedly rough inspection of library symbols.)

As libboost_thread doesn't come in a single thread variant, I'm 
wondering if

libboost_date_time-mt.a
libboost_filesystem-mt.a
libboost_graph-mt.a
libboost_prg_exec_monitor-mt.a
libboost_program_options-mt.a
libboost_python-mt.a
libboost_serialization-mt.a
libboost_signals-mt.a
libboost_test_exec_monitor-mt.1
libboost_unit_test_framework-mt.a
libboost_wave-mt.a
libboost_wserialization-mt.a

And the corresponding shared objects are, in fact, no-ops on linux 
targets? If not, can somebody give me some more insight onto what 
practical difference the *-mt libraries above have from the 
single-thread variant?

best,
